To all whom it may concern:

Be .it known that I, FERDINAND BonoriAR'rz,a subject oftheEmperor'of Germany, and resident of the borough ofiManhattan, city, county, and State of New York, have invented certain new .and useful Improvements in Blocks for Building Construction, of which the following is a specification.

My invention relates to buildingconstruc tion and more particularly to blocks used in the construction of floors and ceilings and has .for its object to provide block sections of suitable material some of which are recessed to accommodate the usual tie rods and others of which are hollow and adapted to fill the space between parallel recessed K sections to form complete hollow blocks. All of said hollbw blocks formed of said sections are arranged to be assembled in a certain correlation to each other. to comprise parts of a complete floor or ceiling which is light and fireproof andris possessed of great stability and-"strength, Other objects of from the construction'hereinaften described, a nrkti e features of novelty will be pointed out in"ith'4 e., appended claims.

Reference-"is to be had to ing drawings in which- Figure l saplan view partly in section of a floor constructed according to my invention before the cement is introduced; Fig; '2 1s a cross sectlon thereof, on the line 22 of Fig. 1, after the cement has been added;

and Fig. 3 is a cross section of another ar-.

rangement.

Referring to the 'form of my invention shown in Figs. 1,2 and-3, I' provide hollow blocks 8 which are set in position on the temporary scaffolding with their open ends upward and spaced apart so as to form channels extending transversely of each other.- These transversely extending chanextending at an angle of the nels serve to accommodate tie rods 6 and 7.- A second hollow block 9 is arranged to fit within each block 8 with its interior passage sage of the said block 8. This block 9 is so proportioned that its open ends Wlll be engaged and-closed by two opposite walls 10 block S-When'the two blocks are assembled. Each interior block '3 is, however,

block.

my iiivention will appear the accompany} to the interior passomewhat narrower than the inside distance between the two walls ll of each block 8:20 that the walls 11 of the blocks 8 and the side walls of t-he'blocks 9 are spaced from each other. Projections 12 may be provided on the inside of each block 8 for maintaining the respective blocks-9 in position as shown in Fig. 2, or each block 9' may be provided with flanges 13 adapted to engage walls 1L ofeach block 8 as. shown in Fig. 3. In these two forms of my invention each set of blocks 8 and 9 together "form a single hollow block, and are easily manufactured and assembled and when so assembled possessall the advantages of a one piece hollow building, It is to. be understood that in the form of my invention herein shown and described, the block' sections are first assembled in proper relative position on a tem-v porary centering or scaifolding which forms the tempor'arybottom of the transverse channels after which the tie rods are positioned in the said transversely extending channels.' Cement or concrete 14 is then also introduced, therein as well as in to the spaces between the'walls 11' of the block 8 and the side walls of the block 9. This cement may also extend-over or cover thesaid block sections as shownin Fig. 2. a

'My improvements thus provide blocks comprising a plurality of parts, which, as beforestated, are easily and cheaply manutactnred and are readily assembled to form complete, hollow blocks and a solid light and extremely strong floor or ceiling construction. The dead weight of a floor or ceiling of this descr ptionis much lcss tian even in which a hollow block which is manufactured complete in one piece is incorporated. Blocks of the latter description, that is to say one piece hollow blocks are almost always' necessarily provided with strengthening partitions or with walls so thick that'only a comparatively small saving in weight is secured. l urthermore, by constructing the hollow blocks in sections, the component parts are more easily packed forstorage or shipping purposes- This results in a saving of space and owing to the compactness with which said parts may be arranged, also reduces the danger of breakage to a minimum.

Jinfloors' in which a solid block i'llii xl or It-will be understood that changes in the specific constructions shown and described may be'made within thescopebf the claims without departing from the spirit of my invention.

I claim as my invention:

1. A building block comprising a tubular block section and a second tubular block section arranged to completely surround the first-named section to form therewith a complete building block, the axes of said sections v extending at substantially right angles to each other. i r o A building blockbomprising a tubular block section, a second tubular block section arranged to fit Within the first named sec tion and to form therewith a completed block, the axes of said block sections extending at substantially right angles to each, I other and projections on one of said block sections arranged to space the adjacent Walls of said sections, apart.

3. A building block comprisin a tubular block seetion,-a second tubular block section arranged'to fit Within the firstnamed section to form therewith a completed block, the axes of said sect-ions extending at sub,- stantially right angles to each other and flanges on opposite sides of said interior block section, extending parallel With the axis of said section, and projecting out- Wardly therefrom to engage the adjacent walls of the. outer section.

In testimony whereof I have hereunto set G. V. RASMUBSEN.
